Working with its affiliate, the Sabarmati Ashram Gaushala
in Bidaj, Gujarat, the National Dairy Development Board
operates an Open Nucleus Breeding System (ONBS)
project for Sahiwal X Holstein Friesian crossbreds since
1994. Bulls are evaluated under a nucleus breeding scheme
using Multiple Ovulation and Embryo Transfer as an alternative
to progeny testing.
The Open Nucleus Breeding
System offers the advantage of testing bulls under
controlled farm conditions.
Since under ONBS sires and
dams are evaluated on the basis of their sib performance
and not on their progeny programme, such evaluations
accelerate genetic gain as the generation interval goes
down.
